Obviously I was being cheeky about the vaginal international border, but now I'm being serious. Many on the left are advancing this 37 gender rhetoric, and the result is that it necessitates the deconstruction of traditionally recognized "women's" issues. J.K. Rowling has been lambasted (mostly with emotional temper tantrums and straw man arguments) for her positions on this subject, but she's been wonderfully articulate on it. When you re-define what constitutes a "girl" or a "woman" you take away protections for girls and women by allowing boys and men to invade those protections.
The left are going to need to reconcile their rhetoric. Abortion cannot be a "women's" issue in a 37 gendered world.
